Specification of Letters Patent.

Patented Sept. ill, r91 t.

Application filed August 31, 1914. Serial No. 859,428.

To all whom it may concern:

Be it known that I, Isaac FRANCIS TAY- LOR, engineer, a subject of theKing of Great Britain and Ireland, residing at 5 Upland road, EastDulwich, London, S. E, Eng: land, have invented certain new and usefulImprovements in Apparatus for Storing Ships Boats and Facilitating theLowering of Same, of which the following is a specification.

This invention has for its object to enable boats to be stored or stowedon ships in such a manner that they can be quickly lowered by the davitsor launching appa ratus simultaneously from both sides of the ship orthe whole of the boats be readily brought into position for lowering oneither side ofthe ship, so that all boats can be lowered even when theweather conditions are such that launching can only be safely affectedfrom one side of the ship.

Other objects are to enable the boats to be launched with safety andgenerally to enable the lowering or raising as well as the trimming ofthe boat to be effected and controlled with greater ease and facilitythan heretofore.

According to this invention a track is arranged around or partly aroundthe boat deck and coupled trolleys are mounted to run on the track eachtrolley being constructed to carry one or more boats. Ropes or chainsare carried around the t 'ack in opposite directions on guide pulleys orrollers to winch or like winding barrels by which means the trolleys canbe caused to travel over the track and in the case of an endless trackentirely around the track in either direction, one hauling rope beingunwound as the other is Wound up on its barrel. Means are also providedfor locking the winding barrels against rotation to hold the trolleysstationary, or for locking the trolleys independently.

The loweringand raising of the boats is controlled by a winch comprisinga pair of winch barrels with brake drums and one feature of the presentimprovements consists in gearing the barrels together in such mannerthat they can be rotated simultaneously at the same rate to Wind up orpay out the falls as required or readily disconnected and allowed torotate at difierent speeds under the control of the drums when the boatis being lowered to trim the boat The winch cooperates with davits ofthe pivoted. cantalivor type as set forth in our prior British patentspecification ilo. 2224-2/12, and the present invention also comprisesimproved means whereby the cantahvers are automatically swung outward bythe pull of the falls at the beginning of the boat lowering operation,and im proved means for locking the cantalivers in their outboardposition.

Our invention also provides guides for guiding the boats down the shipsside during the lowering of same.

In the accompanying drawings Figure 1 is a plan of boat storing andlaunching apparatus constructed according to this invention.

Figs. 2 and 3 are side elevations on a larger scale of the davits andlaunching tackle shown in the inboard and outboard positionsrespectively.

Fig. 4 is a side elevation of a double barreled winch provided withcontrolling gear in accordance with this invention.

Fig. 5 is a transverse section showing certain details of thecontrolling gear.

Fig. 6 is an end view of one of the boat carrying trolleys showing twoboats in position on the trolley.

Fig. 7 is a transverse section of the trolley, 011 a larger scale.

Fig. 8 is a plan of a trolley.

Figs. 9 and 10 are a detail elevation and plan respectively of doublerope couplings for connecting the hauling ropes to the trolleys, and

Figs. 11 and 12 are similar views of single rope couplings.

As shown the track is composed of parallel rails o the end or othersections a of the track being hinged or detachable if desired so as tobe capable of being raised or removed to afford access to hatchways orthe like where necessary. Each rail has a vertical web portion a and ahorizontal tread portion a which is embraced by swiveling underfrainemembers I) on the trolleys a which hold the trolleys in positionlaterally and vertically on the rails; If desired heating pipes a may berun alongside the track to prevent freezing of water on the track incold latitudes.

Each trolley comprises as shown in Figs.

collapsible iron and stays or brace members 0 0 connected with the platea and-bearing members 0 in which the wheels and guide rollers 6 72 b aremounted. Horizontal extensions on the lower ends of the bearing memberL0 project under the rail treads and thereby prevent the trolleysleaving the rails. A single lateral guide roller 5 bears against theinner side of the track to facilitate the running of the trolley aroundcurves, but acting on the outer rail there are three lateral guiderollers b which insure the proper guiding of the swiveling carriers. Theupper parts of the trolleys form chocks for the boats and areconstructed of longitudinal and transverse channel iron members (Z, clconnected by a central swivel bolt d with the underframe and providedwith shoes or blocks (Z to slide on the plate 0' or with rollers, andwhere it is desired to support two or more boats one above another,swiveling or movable arms a forming checks are supported at di'lferentheights by hinged bars 7' on the arms which pass over pins 7 on thetrolley frame and are secured by cotters in such a manner that after theuppermost boat has been launched from a trolley, the arms or choclzs 6can be released by releasing the hinged bars, enabling the arms 6 to beswung out of the way about vertical pivots g on the fixed supportingframe, so that the next boat below can be launched and so on. Asillustrated the upper boat is secured by a rope Z secured at one end toan eye on the pivot f/ and at the other end to an eye on the arm 6. Twoor more trolleys are preferably con-' nected together by coupling barsit which conveniently pivot about the same vertical axes as theswiveling frame members hereinbefore referred to.

The hauling cables 2' or the like are coupled to the pivot bolt 6Z2 ofone of the trolleys by coupling eyes or lugs j as shown in Figs. 9 to 12and pass between the track rails in opposite directions over suitableguide pulleys 7c, and guide rollers'm, m by which they are led overother pulleys m to barrels or drums 11. provided with wind ing cranks orother hand or power driven gear for winding the cables on the barrels.Ratchet teeth 0 are provided on the barrels with which pawls 0 can beengaged to pre-- vent rotation of the barrels in the unwinding directionand thus hold the trolleys in any position on the track which theymay berequired a to occupy.

It will be seen that when moving the trolleys on the track in eitherdirection one of the hauling cables will be wound up on one winch barrelwhile the other is unwound from the other barrel. Any number of trolleysmay be connected at any part of the track to a cable 2" passing aroundthe track and attached to one of the trolleys at the same point as thewinch cables. For this purpose a double coupling lug is provided asshown in Figs. 9 and 10, for the connection of the two cables, and asingle 00l-1P'll11gitS shown in Figs. 11 and 12 where it is onlynecessary to attach a single cable.

As illustrated in Figsl' and -L the winch barrels p, p which effect thelowering or raising of the boat'srane mounted in asuitable frame Q withtheir axes in line and actuated by independent.shafts 1" 1" eachprovided with a crank or other means of directly applying manual powerto the shafts.

Hand operated countershafts r r are also provided for applying power. tothe winches and geared with the winch barrels by spur gearing s 8. Anysuitable motive power may also be employed tooperate the winches as anauxiliary to the fmanual power. The shafts r r are mounted to slidelongitudinally. inthe winch frame to enable their spur wheels 8 to bemoved out of gear with the. winch barrels when desired in which positionthey are held by suitable catches r engaging collars on the shafts.

These shafts may also be actuated through worm gear, in which case aworm wheel would be mounted on the shaft and driven by a worm spindleoperated by. hand or power. The parts of the shafts on which the wormwheels are mounted are made square or provided with a feather andon theshaft on opposite sides of the worm wheel to take the thrust of the wormand provided with. roller or ball races. Brake drums t t are arrangedonthe ends of the winch barrels, and are acted upon by brake bands 25 (ioperated by foot levers t t to control the lowering of theboats. a Inaddition to the actuating shafts aforesaid .anotherishaft'u is providedin the winch frame which carries a pair of spur wheels a 2& adapted tobe put in mesh with the spur gear wheels 8 on the winch barrelsto gearthe barrels together or to be moved'out of 4 gear therewith leavingthebarrelsfree to rotate independently under the control. of

- the cranks or brake drums to pay. out. the

falls according to thetrimto be given to the boat; For thispurpose theshaft a carrying the spur. wheels is mounted to slide longitudinally inthe winch frame and is moved in one direction by an -,angle lever u?pivoted in a bracket a and actuated in one direction by a foot lever'and in the opposite direction by a spring a which normally maintainsthe shaft in gear. i a i As shown in Fig. 5 the lever a has a forked armwhich has apin and slot connection with a collar or block on the shaftu.

r If desired the lowering and trimming of the boats may be controlledfrom a bridge built over the gantry or framing 011 which the davits aresupported. In this case the foot levers controlling the winches would bereplaced by suitable levers, and rodding or other connections leading tohand levers or foot levers or both on the bridge. This arrangement wouldenable the operator to have an unobstructed view of the boat while thesame was being lowered. V

The davits which as clearly illustrated in Figs. 1, 2 and-3 consist ofstayed or braced structures of right angled triangular form, are pivotedat o to a suitable framing which extends over the track a on the boatdeck and comprise the two main members o o connected at right angles bythe stayo and the inclined braces o '0 Pulleys 'w are mounted on the,davits, and framing over which the falls 20 are guided to the winchbarrels. Means are also providedlon the davits for clamping the falls toto the davit when the davit moves in from the outboard positionconsisting of angle levers a pivoted to the bracing members or stays '0of the davits and adapted'under the action of suitable springs 00 toclamp the falls against the blocks cc? fixed to the stays o As shown thesprings 00 are mounted under the blocks on headed rods :0 which passthrough suitably shaped clamping jaws .022 formed on the ends of thelevers 00. As the davits move into the outboard position these clampinglovers are released by their longer arms coming against fixed stops w.

The clamping levers m are also connected by cords, chains or the like gpassing over pulleys z with a foot lever 2' adapted to release theclamping levers at will when it is desired to raise or lower the fallswithout actuating the davits.

By clamping the falls to the davits as described the pull on the fallsas they are first paid out from the winches to lower the boat will betransferred to the davit structures to swing them about their pivotsinto the outboard position in which position they are held by links 2which engage the davits and form tension stays said links beingpivotally connected at 2 to the fixed framing on which the davits aresupported. Levers 2 are also pivoted on arms or members o of the davitswhich tilt when the davits reach the outboard position so that theirinner ends engage fixed stops m on the davit support and prevent thedavits vbeingvraised again until the launched from v by said davitslocking levers are released. The release is effected when the falls ware wound up to a given height, by weights or balls 10 which engage thelockinglevers 2* and raise their outer ends so that the inner ends ofthe levers are depressed out of engagement with the stops In order toguide the boats when being or raised to the boat deck, angular guidebars 10 are mounted vertically on pivoted links 10 connected with thedavit stand or framing and depend down the ships side a suitabledistance, said bars being suitably spaced apart to engage the boats atthe stem and stern. When not in use the guide bars are capable of beingfolded inboard out of the way.

It will be seen that with the improved apparatus boats can be kept inthe most con venient position for launching by the davits and tacklefrom both sides of the ship, or quickly transferred from one side of theship to the other. The boats may also be easily loaded while in positionon the trolleys be fore being swung outboard and lowered.
